The features, principles, and other aspects of the present disclosureare described in detail below.

An optical imaging lens assembly according to an exemplary embodiment ofthe present disclosure may include, for example, six lenses havingrefractive power, i.e. a first lens, a second lens, a third lens, afourth lens, a fifth lens and a sixth lens. The six lenses are arrangedsequentially from an object side to an image side along an optical axis.

In an exemplary embodiment, the first lens may have a positiverefractive power, an object-side surface thereof may be a convexsurface, and an image-side surface thereof may be a convex surface; thesecond lens may have a negative refractive power; the third lens mayhave a negative refractive power, and an image-side surface thereof maybe a concave surface; the fourth lens has a positive refractive power ora negative refractive power; the fifth lens has a positive refractivepower or a negative refractive power, and an image-side surface thereofmay be a convex surface; and the sixth lens has a positive refractivepower or a negative refractive power, and an image-side surface thereofmay be a concave surface.

In an exemplary embodiment, an image-side surface of the fourth lens maybe a concave surface.

In an exemplary embodiment, the sixth lens may have a negativerefractive power, and an image-side surface thereof may be a concavesurface.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: HFOV<30°, where HFOV is half of amaximal field-of-view of the optical imaging lens assembly. Morespecifically, HFOV may further satisfy: HFOV<25°, for example,24.1°≤HFOV≤24.2°. By reasonably controlling the half of a maximalfield-of-view of the optical imaging lens assembly, the optical systemmeets the telephoto characteristics and has a good ability to correctaberrations.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: f1/CT4>11, where f1 is aneffective focal length of the first lens and CT4 is a center thicknessof the fourth lens along the optical axis. More specifically, f1 and CT4may further satisfy: 11<f1/CT4<15, for example, 11.20≤f1/CT4≤13.45. Byreasonably controlling the ratio of the effective focal length of thefirst lens to the center thickness of the fourth lens, the opticalsystem satisfies the telephoto characteristic and has a better abilityto balance aberrations. Further, by reasonably controlling thedeflection angle of the chief ray, the matching degree between the lensassembly and the chip is improved, which is beneficial to adjust thestructure of the optical system.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: −1.3<f/f2<−0.3, where f is atotal effective focal length of the optical imaging lens assembly and f2is an effective focal length of the second lens. More specifically, fand f2 may further satisfy: −1.18≤f/f2≤−0.47. Reasonably setting theeffective focal length of the second lens helps to increase the focallength of the optical system and realize the telephoto characteristic ofthe lens assembly. Further, by reasonably setting the effective focallength of the second lens, the position of the light may be effectivelyadjusted, which is beneficial to shorten the total length of the opticalimaging lens assembly.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: −2.2<f3/f<−0.6, where f3 is aneffective focal length of the third lens and f is a total effectivefocal length of the optical imaging lens assembly. More specifically, f3and f may further satisfy: −2.11≤f3/f≤−0.73. By reasonably configuringthe effective focal length of the third lens, the telephotocharacteristic of the lens assembly may be achieved while theaberrations are corrected. Further, the total length of the opticalsystem is effectively shortened to meet the requirements for thinnessand lightness.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 2<f/f1<2.5, where f is a totaleffective focal length of the optical imaging lens assembly and f1 is aneffective focal length of the first lens. More specifically, f and f1may further satisfy: 2.26≤f/f1≤2.35. Reasonably setting the effectivefocal length of the first lens helps to achieve the telephotocharacteristic of the lens assembly. Moreover, by reasonably controllingthe refractive power of the first lens, the ability of the imagingsystem to converge light may be improved, and the focus position of thelight may be adjusted, thereby helping to shorten the total length ofthe system.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 1<(R2−R1)/(R2+R1)<1.5, where R2is a radius of curvature of the image-side surface of the first lens andR1 is a radius of curvature of the object-side surface of the firstlens. More specifically, R2 and R1 may further satisfy:1.15≤(R2−R1)/(R2+R1)≤1.45. Reasonably assigning the radius of curvatureof the object-side surface and the image-side surface of the first lenshelps to adjust the refractive power distribution on both sides of thefirst lens, and helps to improve the ability of the optical system tocompensate astigmatic.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 0.2<R6/f<1.2, where R6 is aradius of curvature of the image-side surface of the third lens and f isa total effective focal length of the optical imaging lens assembly.More specifically, R6 and f may further satisfy: 0.31≤R6/f≤1.03. Byreasonably arranging the radius of curvature of the image-side surfaceof the third lens, the astigmatic of the system may be effectivelycompensated, the back focal length of the system is shortened, and theminiaturization of the optical system is further ensured.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 3.7<CT1/CT3<4.7, where CT1 is acenter thickness of the first lens along the optical axis and CT3 is acenter thickness of the third lens along the optical axis. Morespecifically, CT1 and CT3 may further satisfy: 3.91≤CT1/CT3≤4.52.Reasonably controlling the ratio of the center thickness of the firstlens to the center thickness of the third lens may effectively reducethe size of the optical system, and avoid the excessively large systemvolume. At the same time, the assembly difficulty of the lens may beeffectively reduced and a higher space utilization rate may be achieved.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 2<T56/CT6<3.5, where T56 is aspaced interval between the fifth lens and the sixth lens along theoptical axis and CT6 is a center thickness of the sixth lens along theoptical axis. More specifically, T56 and CT6 may further satisfy:2.02≤T56/CT6≤3.39. By reasonably controlling the ratio of the airinterval between the fifth lens and the sixth lens along the opticalaxis to the center thickness of the sixth lens, the size of the systemmay be effectively reduced, and the telephoto characteristic of the lensmay be achieved. At the same time, the structure of the system isadvantageously adjusted, and the difficulty of lens processing andassembly is reduced.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: −1.6<f6/f<−0.6, where f6 is aneffective focal length of the sixth lens and f is a total effectivefocal length of the optical imaging lens assembly. More specifically, f6and f may further satisfy: −1.3<f6/f<−1.0, for example,−1.26≤f6/f≤−1.03. Reasonably setting the effective focal length of thesixth lens is beneficial to increase the focal length of the opticalsystem and ensure the telephoto characteristic of the system.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 0.5<T34/TTL*10<1, where T34 is aspaced interval between the third lens and the fourth lens along theoptical axis, and TTL is a distance along the optical axis from a centerof the object-side surface of the first lens to an imaging plane of theoptical imaging lens assembly. More specifically, T34 and TTL mayfurther satisfy: 0.64≤T34/TTL*10≤0.92. Reasonably controlling the ratioof the air interval along the optical axis between the third lens andthe fourth lens to the axial distance from the object-side surface ofthe first lens to the imaging plane helps to ensure that the opticalsystem has light and thin characteristics and telephoto characteristics,so that the imaging lens assembly may be used in high-performanceportable electronic products with a wide-angle lens.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 0.5<T23/CT2<1.8, where T23 is aspaced interval between the second lens and the third lens along theoptical axis, and CT2 is a center thickness of the second lens along theoptical axis. More specifically, T23 and CT2 may further satisfy:0.58≤T23/CT2≤1.76. By reasonably controlling the ratio of the airinterval along the optical axis between the second lens and the thirdlens to the center thickness of the second lens, a sufficient space isprovided between lenses, so that the lens surface may have a higherdegree of freedom of change, and thus improve the system's ability tocorrect astigmatic and field curvature.

In an exemplary embodiment, the optical imaging lens assembly accordingto the present disclosure may satisfy: 0.5<(R10−R11)/(R10+R11)<1.5,where R10 is a radius of curvature of the image-side surface of thefifth lens and R11 is a radius of curvature of an object-side surface ofthe sixth lens. More specifically, R10 and R11 may further satisfy:0.6<(R10−R11)/(R10+R11)<1.1, for example, 0.65≤(R10−R11)/(R10+R11)≤1.00.Reasonably distributing the radius of curvature of the image-sidesurface of the fifth lens and the object-side surface of the sixth lens,and making the image-side surface of the fifth lens convex and theobject-side surface of the sixth lens concave, helps the optical systemto better match the chief ray angle of the chip.

In an exemplary embodiment, the optical imaging lens assembly describedabove may further include at least one stop to improve the imagingquality of the lens assembly. The stop may be disposed at any positionas needed, for example, the stop may be disposed between the object sideand the first lens.

Optionally, the above optical imaging lens assembly may further includean optical filter for correcting the color deviation and/or a protectiveglass for protecting the photosensitive element on the imaging plane.

The disclosure proposes a six-piece telephoto lens assembly that usesaspheric lens. The wide-angle and telephoto lens assembly cooperate toachieve the purpose of zooming, so as to obtain an image with suitablemagnification and good quality in the form of autofocus, thereby makingthe lens suitable for shooting objects at distant. At the same time, thelens assembly of the present disclosure by properly assigning therefractive power of each lens, the surface shape, the center thicknessof each lens, and spaced intervals on the optical axis between thelenses, the size and the sensitivity of the imaging lens assembly may beeffectively reduced, and the workability of the imaging lens assemblymay be improved, such that the optical imaging lens assembly is moreadvantageous for production processing and may be applied to portableelectronic products.

In the embodiments of the present disclosure, at least one of thesurfaces of each lens is aspheric. The aspheric lens is characterized bya continuous change in curvature from the center of the lens to theperiphery of the lens. Unlike a spherical lens having a constantcurvature from the center of the lens to the periphery of the lens, theaspheric lens has a better curvature radius characteristic, and has theadvantages of improving distortion aberration and improving astigmaticaberration. With aspheric lens, the aberrations that occur duringimaging may be eliminated as much as possible, and thus improving theimage quality.

However, it will be understood by those skilled in the art that thenumber of lenses constituting the optical imaging lens assembly may bevaried to achieve the various results and advantages described in thisspecification without departing from the technical solution claimed bythe present disclosure. For example, although the embodiment isdescribed by taking six lenses as an example, the optical imaging lensassembly is not limited to include six lenses. The optical imaging lensassembly may also include other numbers of lenses if desired.

Some specific examples of an optical imaging lens assembly applicable tothe above embodiment will be further described below with reference tothe accompanying drawings.

As can be seen from Table 1, the object-side surface and the image-sidesurface of any one of the first lens E1 to the sixth lens E6 areaspheric. In this example, the surface shape x of each aspheric lens maybe defined by using, but not limited to, the following aspheric formula:

$\begin{matrix}{x = {\frac{ch^{2}}{1 + \sqrt{1 - {\left( {k + 1} \right)c^{2}h^{2}}}} + {\sum{Aih}^{i}}}} & (1)\end{matrix}$

Where, x is the sag—the axis-component of the displacement of thesurface from the aspheric vertex, when the surface is at height h fromthe optical axis; c is a paraxial curvature of the aspheric surface,c=1/R (that is, the paraxial curvature c is reciprocal of the radius ofcurvature R in the above Table 1); k is a conic coefficient (given inthe above Table 1); Ai is a correction coefficient for the i-th order ofthe aspheric surface. Table 2 below shows high-order coefficients A4,A6, A8, A10, A12, A14, and A16 applicable to each aspheric surfaceS1-S12 in example 1.
